Heating up through the start of fall

Moisture has moved into Southern California thanks to a southeasterly flow. Dew point temperatures have climbed into the 50s and 60s, creating a humid day in the Coachella Valley. The additional moisture and heat have led to the development of showers over the San Jacinto Mountains. Some sprinkles were even pushed east into the desert.

The humid environment will follow us into the weekend as a ridge of high pressure builds over the Desert Southwest, steering in the sticky conditions. The same ridge will aid in temperatures climbing 5-10° above the seasonal average for the first fall weekend.

An Excessive Heat Warning will take effect at 11:00 a.m. Sunday as temperatures continue their upward climb. Highs could reach as high as 110° through Tuesday.

Don't let the heat catch you off guard just because it's fall. Take note of the signs and symptoms of heat-related illnesses so you can take action quickly.
